Book Description
Formaldehyde is widely present in the environment and is one of the highest production chemicals by volume, used in manufactured goods including wood products, permanent press fabrics, and household products. It is also formed by combustion sources and is present in smoke from cigarettes and other tobacco products, and in emissions from gas stoves and open fireplaces. In carrying out its mission to protect human health, the U.S. Environmental Protection Agency (EPA) identifies and characterizes the health hazards of chemicals found in the environment through its Integrated Risk Information System (IRIS) Program, which has reviewed the human health hazards resulting from formaldehyde exposure in several assessments. This report is a continuation of guidance from the National Academies on draft IRIS assessments of formaldehyde and other aspects of the IRIS program. This report reviews the 2022 Draft Assessment with regard to its adequacy and transparency in evaluating the scientific literature, use of appropriate methods to synthesize the current state-of-the science, and presentations of conclusions that are supported by the scientific evidence. The report concludes that the 2022 Draft Assessment follows the advice of prior National Academies reports and that its findings on hazard and quantitative risk are supported by the evidence identified. However, revisions are needed to ensure that users can find and follow the methods used in each step of the assessment for each health outcome.

Review of EPA's 2022 Draft Formaldehyde Assessment
Review of the Environmental Protection Agency's Draft IRIS Assessment of Formaldehyde
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309211964
Category : Science
Languages : en
Pages : 204
Book Description
Formaldehyde is ubiquitous in indoor and outdoor air, and everyone is exposed to formaldehyde at some concentration daily. Formaldehyde is used to produce a wide array of products, particularly building materials; it is emitted from many sources, including power plants, cars, gas and wood stoves, and cigarettes; it is a natural product in come foods; and it is naturally present in the human body as a metabolic intermediate. Much research has been conducted on the health effects of exposure to formaldehyde, including effects on the upper airway, where formaldehyde is deposited when inhaled, and effects on tissues distant from the site of initial contact. The U.S. Environmental Protection Agency (EPA) released noncancer and cancer assessments of formaldehyde for its Intergated Risk Information System (IRIS) in 1990 and 1991, respectively. The agency began reassessing formaldehyde in 1998 and released a draft IRIS assessment in June 2010. Given the complexity of the issues and the knowledge that the assessment will be used as the basis of regulatory decisions, EPA asked the National Research Council (NRC) to conduct an independent scientific review of the draft IRIS assessment. In this report, the Committee to Review EPA's Draft IRIS Assessment of Formaldehyde first addresses some general issues associated with the draft IRIS assessment. The committee next focuses on questions concerning specific aspects of the draft assessment, including derivation of the reference concentrations and the cancer unit risk estimates for formaldehyde. The committee closes with recommendations for improving the IRIS assessment of formaldehyde and provides some general comments on the IRIS development process.

Pages : 266
Book Description
“No journalist knows more about toxic chemicals in the workplace than Jim Morris. The Cancer Factory is the crowning achievement of his estimable career spent walking fence lines, factory floors, and doctor’s offices.” —Dan Fagin, author of the Pulitzer Prize–winning Toms River “The Cancer Factory could not come at a better time, as we reckon with how our bodies pay the price for our nation’s toxic history and as today’s workers fight not for only their rights but for their very lives.… A powerful and essential read.” —Anna Clark, author of The Poisoned City The story of a group of Goodyear Tire and Rubber workers fatally exposed to toxic chemicals, the lawyer who sought justice on their behalf, and the shameful lack of protection our society affords all workers Working at the Goodyear Tire and Rubber Company chemical plant in Niagara Falls, New York, was considered a good job. It was the kind of industrial manufacturing job that allowed blue-collar workers to thrive in the latter half of the 20th century—that allowed them to buy their own home, and maybe a small boat for the lake. But it was also the kind of job that exposed you to toxic chemicals and offered little to no protection from them, either in the way of protective gear or adequate ventilation. Eventually, it was a job that gave you bladder cancer. The Cancer Factory tells the story of the workers who experienced one of the nation’s worst, and best-documented, outbreaks of work-related cancer, and the lawyer who has represented the bladder-cancer victims at the plant for more than 30 years. Goodyear, and its chemical supplier, DuPont, knew that two of the chemicals used in the plant had been shown to cause cancer, but made little effort to protect the plant’s workers until the cluster of cancer cases—and deaths—was undeniable. In doing so it tells a broader story of corporate malfeasance and governmental neglect. Workers have only weak protections from exposure to toxic substances in America, and regulatory breaches contribute to an estimated 95,000 deaths from occupational illness each year. Based on 4 decades of reporting and delving deeply into the scientific literature about toxic substances and health risks, the arcana of worker regulations, and reality of loose enforcement, The Cancer Factory exposes the terrible health risks too many workers face.

Languages : en
Pages : 130
Book Description
Over the past several years, the US Environmental Protection Agency (EPA) has been transforming the procedures of its Integrated Risk Information System (IRIS), a program that produces hazard and doseâ€'response assessments of environmental chemicals and derives toxicity values that can be used to estimate risks posed by exposures to them. The transformation was initiated after suggestions for program reforms were provided in a 2011 report from the National Academies of Sciences, Engineering, and Medicine that reviewed a draft IRIS assessment of formaldehyde. In 2014, the National Academies released a report that reviewed the IRIS program and evaluated the changes implemented in it since the 2011 report. Since 2014, new leadership of EPA's National Center for Environmental Assessment (NCEA) and IRIS program has instituted even more substantive changes in the IRIS program in response to the recommendations in the 2014 report. Progress Toward Transforming the Integrated Risk Information System Program: A 2018 Evaluation reviews the EPA's progress toward addressing the past recommendations from the National Academies.

Formaldehyde
Author: Luoping Zhang
Publisher: Royal Society of Chemistry
ISBN: 1782629734
Category : Medical
Languages : en
Pages : 414
Book Description
Formaldehyde is virtually ubiquitous in the modern environment due to its cost-effective nature, its use in resin formation, and its preservative properties. Though formaldehyde is necessary for many products and processes important to the world’s economy, this economic dependence on formaldehyde comes at a cost to public health. Growth and consequent industrialization rely heavily on formaldehyde use. New buildings—residences, public places, and offices—are not only built with timber preserved by formaldehyde, but they are also furnished with wood, wool, and textile products that contain formaldehyde. The general population faces environmental exposure from indoor and outdoor air pollution, food, and even medicine. Scientific inquiry into formaldehyde exposure has grown in response. This book consolidates the new and established body of formaldehyde research in the scholarly community, focusing on exposure, genotoxicity, and adverse health outcomes. Through this resource, we hope to increase awareness of the broad range of health effects posed by formaldehyde exposure, and to encourage interdisciplinary interest, as well as research, into this pervasive compound—especially in the United States and China, where formaldehyde production and usage is high. This book will be useful to researchers of environmental and occupational exposure, students, and government regulators and anyone exposed to formaldehyde in the workplace and/or at home.

Pages : 596
Book Description
Principles of Toxicology concisely and efficiently presents the scientific basis for toxicology as it applies to the workplace and the environment, covering diverse chemical hazards encountered in modern workplaces and natural environments and providing a practical understanding of these hazards for those concerned with protecting the health of humans and ecosystems. The work presents not only theory, but also practical information regarding chemical hazards to give the student and new professional a working knowledge of the practice of toxicology and the ability to solve problems in environmental and industrial settings. Case histories and examples from industrial and environmental exposures to chemicals are included to demonstrate the application of toxicological principles. To allow for seamless reader comprehension and further exploration of covered topics, the work is supplemented with numerous illustrations to clarify and summarize key points, as well as annotated bibliographies. In the 4th edition, all chapters and references have been updated to account for the latest scientific thinking, and new color figures have been added. New topics covered in 4th Edition of Principles of Toxicology include: Regulatory toxicology, including the key regulatory framework in which much of the field of toxicology operates Alternative methods in toxicology, including cutting-edge approaches to developing new information on the toxicity of drugs and chemicals The dilemma of selecting safe exposure limits, guiding readers through practical considerations and pitfalls in developing and using safe exposure limits Ecological risk assessment, with detailed discussion of methods and considerations when evaluating the effects of contaminants on plants and animals. Providing information on the principles of toxicology and the application of those principles to solve problems in environmental and industrial settings, Principles of Toxicology serves as an excellent textbook resource for advanced undergraduate, graduate, and professional students in a range of environmental and health fields. It is also valuable to health professionals who need toxicological information and assistance beyond what is found in an introductory text to general toxicology.

Review of EPA's Integrated Risk Information System (IRIS) Process
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309304172
Category : Political Science
Languages : en
Pages : 227
Book Description
The Integrated Risk Information System (IRIS) is a program within the US Environmental Protection Agency (EPA) that is responsible for developing toxicologic assessments of environmental contaminants. An IRIS assessment contains hazard identifications and dose-response assessments of various chemicals related to cancer and noncancer outcomes. Although the program was created to increase consistency among toxicologic assessments within the agency, federal, state, and international agencies and other organizations have come to rely on IRIS assessments for setting regulatory standards, establishing exposure guidelines, and estimating risks to exposed populations. Over the last decade, the National Research Council (NRC) has been asked to review some of the more complex and challenging IRIS assessments, including those of formaldehyde, dioxin, and tetrachloroethylene. In 2011, an NRC committee released its review of the IRIS formaldehyde assessment. Like other NRC committees that had reviewed IRIS assessments, the formaldehyde committee identified deficiencies in the specific assessment and more broadly in some of EPA's general approaches and specific methods. Although the committee focused on evaluating the IRIS formaldehyde assessment, it provided suggestions for improving the IRIS process and a roadmap for its revision in case EPA decided to move forward with changes to the process. Congress directed EPA to implement the report's recommendations and then asked the National Research Council to review the changes that EPA was making (or proposing to make) in response to the recommendations. Review of EPA's Integrated Risk Information System (IRIS) Process provides an overview of some general issues associated with IRIS assessments. This report then addresses evidence identification and evaluation for IRIS assessments and discusses evidence integration for hazard evaluation and methods for calculating reference values and unit risks. The report makes recommendations and considerations for future directions. Overall, Review of EPA's Integrated Risk Information System Process finds that substantial improvements in the IRIS process have been made, and it is clear that EPA has embraced and is acting on the recommendations in the NRC formaldehyde report. The recommendations of this report should be seen as building on the progress that EPA has already made.
